This can be used to print the modification time, like `stat` with some options. The reason is that `stat` has caused us a number of portability headaches: 1. It's not available everywhere by default 2. The versions are quite different For instance, with GNU stat it's `stat -c '%Y'`, with macOS it's `stat -f %m`. So now checking a cache file can be done just with builtins.
